Ch 12 4. Assume you purchased a corporate bond at its current market price of $1900 on January 1, 2019. It pays 6 percent interest annually on December 31 and will mature on December 31, 2025, at which time the corporation will pay you the face value of $2,000. a. Determine the current yield on your bond investment at the time of purchase. Current yield = Interest income ÷ Current market value Current yield = $60 divided by $1900 = 3.16 percent

The message m(t) is applied to a frequency modulator with sensitivity 7.8 Hz/V and unmodulated carrier frequency of 2000Hz. m(t) = 2.3t[u(t) - u(t - 2.5)] Find the peak frequency deviation defined as the maximum deviation from the unmodulated carrier frequency. The answer should be a number rounded to 5 decimal digits (the minus sign is accepted while other symbols like % are not)
